Procedures for Developing Multi-Period Response Spectra at Non-Conterminous United States Sites (FEMA P-2078)

The resource provides detailed information on the development of probabilistic multi-period response spectra (MPRS) for seismic hazard analysis. It describes the study approach and methods for developing MPRS based on parameters such as SS, spectral response ratio (RS/1), and long-period transition period (TL). The process involves selecting representative short-period and long-period response spectrum shape parameters (RSSPs), determining response domains, calculating MPRS, and blending short-period and long-period responses to derive mid-period MPRS. Site-specific MPRS for maximum considered earthquake ground motions are developed based on the probabilistic and deterministic MPRS in accordance with ASCE 7-16 requirements.
